Kevin: Good piece looking at location and social networking. I've started using FourSquare recently, and as a Nokia smartphone owner, I suffer from lack of a native app. I know that I'm just starting to scratch the surface of it, but for me, FourSquare is too narrowly pitched. I find the game element artificial. FourSquare has a lot of mindshare at the moment, but for me Twitter has more utility. (Having said that I didn't quite see the utility of Twitter when I first started using it.) I do agree that the promoted tweets based on your location has great potential as a revenue stream for Twitter.
Kevin: John Naughton has an excellent meditation about the internet and the pervasive search for easy answers. We're living through a revolution. Get used to it. As he writes, disruption is a feature not a bug. "By implementing these twin protocols, Vint Cerf and Robert Kahn created what was essentially a global machine for springing surprises." It's an excellent piece that looks at a number of the disruptive trends online such as how to deal with information abundance, which upends traditional economics that attempts to deal with the allocation of scrace resources.
